    I have some footage that I need to key that was taped using the Panasonic VariCam in 720p 59.94. I will be capturing this footage using the Panasonic DVCPro HD1200 Deck. If I capture in 720p, it will give me a cleaner key, correct?

    I will be compositing this footage with 1080i and maybe even some SD footage. Now, I am dealing with different frame rates. I know FCP6 has a mixed format timeline, but I want and most likely need to, use AE CS3 for most of my compositing. In the end, the final output will end up being 1080i, but I could also go with 720p and upconvert through hardware.

    I am looking for the best way to mix different frame rate footage in AE? Or should I just capture my footage to be keyed in 1080i, so I have all the same frame rates?

    In the past when I used 720p and put it in a 29.97 fps timeline I get extra frames..?

    Just in case you want to know I am using:
    Mac Pro
    Quad-Core Intel Xeon
    3 GHz
    Memory: 8 GB
    Bus Speed: 1.33 GHz

    Basically my question was, should I capture at 720p or 1080i to key my footage to make my composition. Fotage was taped using a Varicam, which tapes in 720p. My Deck and Card can upconvert it to 1080i. But, my final output will be 1080i, so in the past I have been capturing and keying in 1080i, but I wanted to make sure it was a better way or not.

    As for my workflow being a little off, please elaborate. I would very much like to know. I use AE8 for most of my complicated compositing, and effects. I see more benifits doing this than in FCP.
